As a big manufacturer and exporter in China on the line of electric resistance alloy, we can supply all kinds of electric resistance alloy wire and strips (resistance steel wire and strips),General DescriptionDue to has high tensile strength and increased resistivity values, TANKII copper nickel alloy wires are the first choice for applications as resistance wires. With the different nickel amount in this product range, the characteristics of the wire can be chosen according to your requirements. Copper nickel alloy wires are available as bare wire, or enamelled wire with any insulation and self-bonding enamel. Furthermore, litz wire made of enamelled copper nickel alloy wire are available.Features1. Higher resistance than copper2. High tensile strength3. Good bending proof performanceApplication1. Heating applications2. Resistance wire3. Applications with high mechanical requirements4. OthersSizeWires: 0.018-10mm Ribbons: 0.05*0.2-2.0*6.0mmStrips: 0.05*5.0-5.0*250mm Bars: D10-100mm
